Description
When analyzing marketing data, if we can easily find precedence between A and B that are semantically far from each other, people cannot think of such relationship so that it helps us consider a sales plan focusing on A and B before anyone else do that. Therefore, this paper proposes to define semantic similarity between two items, quantify precedence between two time series data corresponding to these items by using cross correlation, and clarify the gap between the similarity and the precedence as unexpectedness. The proposed method is evaluated with consumer price index data in terms of regression and predictivity.
